如何在iPhone上使用A2DP连接到远程设备

Question

I want to connect to a Bluetooth device and have my app send to it audio over A2DP. So my question is:

• How to scan for a bluetooth device?
• How to pair with it ?
• How to send audio to the paired device?

I am familiar with Corebluetooth but its not compatible for Bluetooth that is not low energy, so what framework should i use? Should the user connect the device throw the settings of the app or can my deal with that?

I know there is a lot of questions but all the information that i found was for android.

Thank you!

Hi let me answer your questions one by one

first of all you dont use CoreBluetooth

you will use AVFoundation and/or CoreAudio (which is a really huge framework with AudioUnits and AudioQueue and much more)

BUT if you just want to play Audio you may not need to dive into CoreAudio AVFoundation is built on CoreAudio and can easily play and record from Bluetooth devices

How to send audio to the paired device?

Core Audio and AVFoundations both have mechanism for getting and sending audio to Bluetooth Audio devices from/to your iphone

How to scan for a bluetooth device and How to pair with it ?

this is done via Bluetooth Settings in your iphone.you just trun yout BT Speaker ON and search then you Pair it for future use

hope this helps
